WIRE-CUTTING MACHINE.

Application filed July 8, 1924. Serial No. 724,768.

My invention relates to the class of machines employed more especially for cutting wire to certain lengths, and an object of my invention, among others, is the production of a machine of this kind that shall be simple in construction and particularly eflicient in operation.

One form of machine embodying my invention and in the construction and use of in which the objects herein set out, as well as others, may be attained, is illustrated inthe accompanying drawings, in which Figure 1 is a top view of my improved ma chine with parts broken away to show construction.

Figure 2 is a side View of themachine Figure 3 is an end view. Figure 4 is a view in section on aplane denoted by the dotted line 4-4 of Figure 1.

In the accompanying drawings the numeral 5 indicates the driving shaft of my improved machine that is mounted in suitable bearings in posts 6 secured to and rising from a base 7, said shaft having any suitable means for driving it, as a pulley 8 secured thereto. A pinion 9 on the shaft'5 meshes with a gear 10 on a speed controlling shaft 11 and a wire feeding disc 12, secured to the shaft 5, cooperates in the feed of wire with a wire feeding disc 13 secured to a feed shaft 14 having a gear 15 meshing with a gear 16 secured to the driving shaft, and by means of which gear 16 the shaft 14 is driven. V

The shaft 11 isfor the purpose of imparting differential speeds to a feed changing shaft for controlling the speed of operation of a wire cutting member, whereby, the speed of the wire feeding discs 12 and 13 being constant and the rate of feed of wire thereof. being uniform the length of wire that will. be cut will depend upon the rapidity of movement of the wire cutting member, and the rate of movement of the latter being changed the length of the pieces of wire being cut will be changed.

In the mechanism herein shown for accoinplishing this purpose there is embodied a speed changing driving pinion .17 meshing with a speed changing pinion 18 so arranged that it may be caused to mesh with either one of a plurality of feed changing gears 19, 20 or 21 secured to 'a speed changing shaft 22 mounted in suitable bearingsin the machine, in the construction herein shown these bearings being contained in a gear box 323 that houses the speed controlling and speed changing mechanism.

A. speed changing lever 24 is pivotally mounted on a carrier sleeve 25 splined to the shaft 11 for sliding movement thereon, said lever being adapted to engage within notches 26, 27 and 28inthe gear box 23 for the purpose of retaining said lever in any desired position, the lever being p'rovided with a handle 29 as a means for manipulating it.

A cutter rotating gear 30 is secured to the shaft 22 and meshes with a pinion 31 on a connecting shaft 32 that, by means of intermeshing bevel gears 33 imparts rotation to a cutter driving shaft 34 mounted in bearings 35 rising from the base 7 of the machine, and as shown in Figures 1 and 2 of the drawings.

A cutter operating cam 36 secured to the shaft 34 operates a cutter rocker 37 pivotally mounted in standards 38 secured to and rising from the base 7,,the end of said rocker opposite its operating cam having a wire 89 cutter 39 of any suitable construction for severing lengths of wire as such wire is fed to the cutter by means of the wire feed rolls 12 and'13. The rocker 37 may have a roller 40 to engage the cam 36 as a means for re- 5 ducing friction if desired.

In accordance with the provisions of the patent statutes I have described the'principles of operation of my invention, together 7 with the device which I now consider to represent the best embodiment thereof; but I'de sire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and appliedto uses other than those'abovc set out.

1 claim-- 1. In a machine for feeding wire and cutting the same into different lengths, said cutting means including a driven shaft, a second driven shaft, a' plurality of gears of different diameters secured to the second shaft, a sleeve splined on the first shaft, a pinion'fixed to the sleeve, a lever having one end pivotally supported on the sleeve and extending upwardly therefrom, a gear journalled on the lever in mesh with said pinion and movable by the lever to'selectively mesh with the gears on the second shaft and a Wirecutter driven by the second 119 shaft.

r 2. In a machine for feeding wire and cutting the same into difi'erent lengths, said cutting means 1nclud1ng a drlven shaft, a second driven shaft, a plurality of gears of different diameters secured to the. second.

shaft, a sleeve spline'd on the first shaft, a pinion fixed to the sleeve, a lever having one end pivotally supported on the sleeve and extending upwardly therefrom, a gear jourw nalled on the lever in mesh with said pinion and movable by the lever to selectively mesh with the gear on the second shaft, a cam driven by the second shaft and a pivotally mounted cutter arn'i operated by said cam.

3. Ina machine for feeding wire and cutting the same into different lengths, said cutting'niea'ns including a driven shaft, a seconddriven shaft, a plurality of gears of different diameters secured to the second shaft, a sleeve splined on the first shaft, a pinion fixed to the sleeve, a lever having one end pivotally supported .on the sleeve and ezztei'i'ding upwardl therefrom, a gear journalled on the lever in mesh with said pinion and movable by the lever to selectively mesh with the gears on the second shaft and a wire cutter driven by the second shaft, a

casing inclosing the gear mechanism and there being an opening in the top of the casing having notches in one'side of one wall there'of alincd with the gears and in Which notches the lever is received when the gear-'on'th'e lever is relatively engaged with the gears on the second shaft.
